Researcher lays down beside nearly 7-foot silver-coloured sturgeon on boat deck.

On April 22, during its annual survey in the St. Clair-Detroit River System, a US Fish and Wildlife Service (USFWS) research crew from the Alpena Fish and Wildlife Conservation Office tagged, measured, and released a six-foot, 10-inch female sturgeon into the Detroit River, where they estimate it was born in 1920.

They reported the USFWS 240-pound sturgeon is among the largest ever recorded in the US. The Ontario Federation of Anglers and Hunters Fish Registry lists a 168-pound sturgeon caught in the Nottawasaga River in 1982 as the largest reported to them.
